Abstract (en)
[origin: EP1039333A1] A liquid crystal display device comprising: a first substrate (1) made of a transparent material, provided with signal electrodes and/or display electrodes (9) formed on one face thereof; a second substrate (2) made of a transparent material, provided with opposed electrodes (12) formed thereon; and liquid crystal sealed in-between the first substrate (1) and the second substrate (2) oppositely disposed opposite to each other with a predetermined gap interposed therebetween such that each of the signal electrodes or the display electrodes (9) face each of the opposed electrodes (12) so as to form a pixel. Further, a white diffusing film (22) and a reflector (25) are disposed in that order from of the first substrate (1)side on the second substrate (2). The white diffusing film (22) having the characteristics of allowing circularly polarized light to pass therethrough substantially as the circularly polarized light, and having a substantially equal transmittance for light components at respective wavelengths in the wavelength range of visible light, effecting improving whiteness of a reflection-type liquid crystal display device. <IMAGE>
